WALLINGFORD — Police are searching for a man who threatened a pregnant woman with a knife and stole her vehicle during a store robbery early Tuesday.

At 5:52 a.m., Vermont State Police received a 911 call from the manager of the Smart Shop store at 172 North Main St. According to police, the manager, who is six months pregnant, was arriving to open up for the day when she was approached by a man with a knife, who forced her inside the store.

“He did actually threaten her with a knife,” said Detective Sgt. Albert Abdelnour.

The robber forced the manager into the bathroom, stole an undisclosed amount of cash and took the manager’s car keys, police said. Police later recovered the manager’s vehicle on Creek Road in North Clarendon near the Route 4 overpass.

The manager was not injured. There were no other employees or any customers in the store.

Police described the robber as a male, between 5 feet 5 inches tall and 5 feet 9 inches tall with a medium build. The man was dressed entirely in black, including a black mask that completely covered his face.

Anyone who might have seen anything suspicious between 5 and 7:30 a.m. Tuesday, either near the store or where the vehicle was found, is asked to call the state police at 773-9101.
